APPARATUS FOR TILLING THE SOIL.

To all whom it may concern:

Be it known that I, JOSEPH RUBARTH, a subject of the King of Prussia,German Emperor, residing at Munster, Kingdom of Prussia, German Empire,have invented certain new and useful Improvements in Apparatus forTilling the Soil, of which the following a specification.

This invention relates to an apparatus which is designed to till orcultivate the soil and, in combination with other implements, to preparethe ground in such a manner that it becomes ready for garden-culturewhen the apparatus has been once passed over it.

There have already become known machines for tilling the soil whichcomprise a certain number of knives combined to form a plow share. Theapparatus according to this invention differs from these devices ofknown construction by the particular shape of the knife which consistsof a vertical or almost vertical cutting edge which is parallel with thefurrow and further of a curved part which serves for laterallydisplacing the earth cut out without however turning the same upsidedown.

In the accompanying drawings the invention is shown in several forms ofconstruc tion.

Figure 1 shows a single standard in elevation. Figs. 2 and 3 representin cross section two standards of different shape. Fig. 4 showsdiagrammatically how the standards are arranged in a machine. Fig. 5shows in elevation a standard of different construction. Fig. 6 shows inelevation a complete apparatus for tilling the soil.

The standard (Fig. 1), of which several are combined to form anapparatus, has a cutting edge 0. and a curved body I) which isterminated by a horizontal runner (Z. The standard can be inclined atany required angle. A horizontal blade 0 with cutting edges which isarranged at the lower end of the standard at the side of the cuttingedge a serves for maintaining the standard in the ground, forcompensating the lifting strain and for facilitating the cutting of theearth.

manner that it stands at an angle to the body, so that the standard iswedge-shaped in cross section. Usually, four of such standards areattached to an iron frame in a diagonal row so that they cover togetherthe length of a plow share or of a co-lter. In this case the curved bodyI) of the standard can be longer so that it overlaps the cutting edge ofthe next following standard. In this manner each preceding standardprepares for the next standard a furrow-shaped space as indicated inFig. 4 by the dotted lines 6. The cutting edge a can be prolongated asshown in Fig. 5 by means of a chisel-shaped extension h.

Diagonal rows of standards are combined with a plow share or with adisk-shaped plow in such a manner that the standards act as sub-soilplows and serve merely for cutting the sole of the furrow or for cuttingthe soil open in front of the plow share 2' and for turning the earthover and for throwing part of the earth directly into the open furrow,the remaining part of the earth being turned over by the plow share. Iflong dung is used, arms 70 are attached to the iron frame m for pushingthe long dung into the furrow, said arms being arranged either beh1ndthe plow share or 111 front of the standards. The standards can furtherbe used in connection with any other agricultural machine in which case,instead of being mounted upon the plow beam m, they are attached to theframes of the corresponding apparatus. In any case the standards can bearranged so that they can be lifted out of the operative position.

I claim A cultivator blade for tilling the soil comprising incombination a standard having a body curve-d in cross sectionlongitudinally of its length open in front and provided with the frontcutting edge for pushing the earth laterally Without turning the same Inwitness whereof I have hereunto set 1m" upslde down, a homzonta] runnerternnnathand 1n the presence of two wltnesses. lng sz'ud body ahorlzontal blade With cut- 4 L ting edges arranged at the lower end ofthe JOSLPH RUBARTH' standard at the side of the cutting edge ofHt-nesses: the same, substantially as described and JOHANNES SCHROEDER,shown and for the purpose set forth.
